In "Silver on the Tree," Susan Cooper emphasizes a critical message about personal responsibility and empowerment. The reference to Drake no longer being in his hammock symbolizes the end of waiting for others to take action on our behalf. It suggests that individuals must recognize their own potential and the power they hold to influence the world around them.
The mention of children not lying idly while awaiting the second coming reflects the need for active participation in shaping the future. Cooper illustrates that the world belongs to the new generation, who must rise to the occasion and make a difference. The call to action reinforces the idea that everyone has the responsibility to engage and contribute rather than depend on others to lead the way.
